Computer
and Video Games offers the promised (story) first detail on
Deus Ex 3, as the shooter/RPG sequel is previewed in the 200th issue of
print magazine PC Zone, which has begun reaching subscribers in advance of its
release on newsstands this Thursday. The game is under construction at Eidos
Montreal with Deus Ex writer Sheldon Pacotti consulting on the project, and
while Harvey Smith and Warren Spector are not involved, word is it has their
"blessing." According to the article, Eidos Montreal is aware of complaints
about Deus Ex: Invisible War, promising to redress "mistakes" like ammo
type limitations. On the other hand, changes are described that further depart
from Deus Ex canon, and make the project sound more like Gears of War, including combat relying more on player aim than stats, a cover system for
stealth (rather than skulking in shadows), and an auto-healing system for
damage. Thanks Jonas.

You can do that in Thief or Splinter cell, as long as you move from cover to cover. Again, those games already do that, they're just removing some of the more difficult to implement options.

Who said cover systems are easy to implement in the first place? Every interview I've seen about such games(R6 Vegas, Gears of War, etc) has said that its pretty difficult to implement and balance it for difficulty. The cover system is entirely separate from the NPC detection system. Thats the only "copout" I've seen so far if they really did just go with a strict coneview.

The game is a ways off yet, theres plenty of time for them to make changes. I'd suggest you post on their forums if you guys really feel so strongly about it.
